1. Overview Microwave level meter measures level of bulk solids and liquids in the storage vessels without physical contact to measuring material. This model of level meter doesn't need separate output unit, which 4..20mA current output signal is carried by same two wires for power supply. 2. Measurement principle The level meter transmits microwaves at constant intervals, and receives echoes (reflection of transmitted waves) from the surface of material under measurement. The time difference between transmission and reception of microwave is processed by microcomputer to accurately determine level of stored materials. 3. Specifications

6. Installation 6-1. Installation ・ If material surface enter to the blind sector, a stand pipe shall be used to ensure that material surface
can not reach the blind sector of the level meter. But if the material surface will not enter the blind sector, then stand pipe should not be used.
・ If length of stand pipe is longer than required, such that antenna end is not protruded from stand pipe, then it causes malfunction of instrument.
・ When required stand pipe length is longer than antenna, please use cone shape stand and ensure radiation angle including the side beam. Keep radiation free of interference from the stand pipe.
【Recommended height of stand pipe】
Solid: The end of the horn antenna must be protruded a minimum of 10mm(0.39) from the stand pipe. Liquid: The end of the antenna must be protruded a minimum of 25mm(0.98) from the stand pipe.
【Calculation of radiation angle expansion】 Solid ：Distance from meas. reference point × tan16°＋φ98(3.85) (Antenna diameter) Solid ：Distance from meas. reference point × tan28°＋φ56(2.2) (Antenna diameter) Liquid：Distance from meas. reference point × tan48°＋φ45(1.77) (Antenna diameter)

6-2. Mounting direction The spread of the transmitted microwave is different depending on direction of the dot on the antenna.
When silo is empty, turn around the dot direction to find out the best point where the greatest reflection echo can
be received without any noise.
6-3. Installation precautions
・Set the value of 100%(20mA) level so that the blind sector is secured. Setting the 100%(20mA)
level within the blind sector will cause a malfunction of the instrument.
・Avoid too long stand pipe to prevent malfunction of the instrument.
・Do not install instrument close to inlet of material under measurement.
・Do not install any interfering instruments within the side beam, because reflections from beams, pipes,
and other supports within the tank will cause false echoes.

・Provide shielding to minimize noise or unwanted reflections, when crossbeams, and other supports
are installed within the tank.
【False reflections】 In environments where interfering signals are generated, level meter may indicate incorrect measurements results. False reflections up to a certain level of strength can be suppressed by executing the echo learning function. However, the level meter's installed position must be changed if true echoes cannot be received or if the reflection level (measured in dB) is extremely low. When there are obstructions such as crossbeams, pipes, or level switches in the tank, install the level meter in a position where there is no obstruction within its radiation angle.
Important：It is not possible to specify the range of false reflections in dB that can be
suppressed by the learning function because the level of true echo from the surface of material differs depending on the level meter installation conditions and measuring material type. The general guideline for the level of false reflections that can be suppressed by the learning function is one third (1/3) of true echo level.
・Install protection such as a simple roof above the Level Meter to avoid exposure to direct sunlight.

(Rotate counterclockwise or to direction “OPEN"). 7-3. Open the wire entry of terminal block by pushing
on the actuating lever with flat screwdriver. (Recommended flat screwdriver: Axis diameterφ3mm(0.11) and blade tip size 2.6mm(0.1))
7-4. Insert wires as shown on the panel, positive (+) to terminal entry No.1 and negative (-) to terminal No.2. Please wire so that there is no mistake. Release actuating lever of the terminal.
7-5. Connect the ground wire to internal earth ground terminal. 7-6. Attach the LCD adj. unit if it had been installed. 7-7. Screw the cover on tightly.
Important: The size of the acceptable cable is max. 1.25mm2 (0.3mm2 to 1.25 mm2).
(0.01 to 0.49in) Warning: Do wiring when the instrument is powered OFF. Avoid short circuit and reverse polarity. The instrument must be supplied with DC power supply, do not apply different voltage. Tighten the cover and lead outlet firmly after wiring completed.
・The size of a grounding wire must be used larger than 1.25mm mm2 ( 0.49 in)

current settings before execute parameter reset. ・ It is possible to clear echo learning range and strength by using the optional PC software,
but echo learning setting described in article 10-4 does not clear even when reset is executed.
・ There are two reset types described above, but there is menu item "Factory reset" might be displayed. This reset type used at factory setting and user can not apply this reset.

10-6. Current output test Allows you to input simulation value in order to test the functioning of the current output.
Important：When you are ready to end the simulation, click on 'Esc' to return the instrument to the actual level measurement.
※In this manual, only setup steps of the typical parameters have been described.
Please refer to "Instruction manual for LCD adjustment unit" and "Operating manual for adjustment software Matsushima DTM" for other settings.

No. Error code Error type Description Corrective actions
1 E8000 SRAM Error SRAM failure 2 E4000 EEPROM Error EEPROM failure 3 E2000 MIC Error MIC unit failure 4 E1000 Trig Error Trigger signal lost 5 E0800 LCD Error LCD adj. unit failure 6 E0400 Charge Error Charge circuit failure
Turn off device power and turn on again
7 E0200 I2C Checksum error Communication between level meter and LCD adj. unit failed
Ensure LCD adj. unit attached properly
8 S.CPU Level meter not responding No response from level meter Turn off device power and turn on
again
9 S.I2C I2C Checksum error Communication between level meter and LCD adj. unit failed
Ensure LCD adj. unit attached properly
10 E0080 Lost echo
･Reflection echo is currently being detected
･There is no reflection echo ･There is no reflection echo in the
measurement span
・Check whether there are adhesives in the horn antenna. If there is adhesives, clean the horn antenna ・Optimize measurement span
11 E0008 Min. meas. limit over Measured distance is lower than "Min. meas. limit"
12 E0004 Max. meas. limit over Measured distance is higher than "Max. meas. limit".
13 E0002 Upper range limit over (100％ over)
Measured distance exceeds "Upper range limit over (100% over)".
14 E0001 Lower range limit over (0％ over)
Measured distance undergoes "Lower range limit over (0% over)".
Check setting for Min. and Max.meas. limit over, and Upper and Lower range limit over. If you set invalid then error message must be clear. Please note that those settings can be altered by optional PC software only. You can not change by LCD adj. unit
※Error message No.11 to 14 will be displayed, only when appropriate settings are set to "Valid" by PC adjustment software Matsushima DTM. The default settings are "Invalid".
If problem persists, please contact your local Matsushima sales office.
・Confirm whether there is damage on housing etc. ・Tighten the cover and lead outlet ・Tighten the bolt for installation fixture
Every 12 months
2 Check of antenna ・Clean the antenna (Solid: Inside，Liquid: Outside) Every 6 to 12 months Important: Standard periodic inspection interval differs depending on measurement condition and measuring material.
No. Problem Check the following Corrective actions
1 Powered ON the device, but screen is blank
・Are wiring connections correct ? ・Check whether the power is supplied to
the device?
・Correct the wiring ・Supply power to the device
2 Measured level reading higher than material level
・Are there any obstructions between antenna and material surface to be measured ?
・Are there any inlet streams of material under measurement within the radiation angle
・Execute echo learning to mask false echo from the obstacle
・Change the level meter position
3 Measured level reading lower than material level
・ Check whether the material surface entered to the blind sector ?
・Change level meter installation
